In the emergency brake test in which the car was braked suddenly from a travelling speed of 80kmh - the maximum recommended for driving with a space-saver - the stopping distance increased for all four vehicles. The data was produced from a series of comparative tests on four vehicles fitted with the standard wheel/tyre combination and then again when fitted with three standard wheels and one space-saver on the driving axle. "The tests show that braking and handling can be adversely affected by using these different forms of temporary spare tyres." "Our concern is that consumers are unaware of the increasing use of these spare wheels and secondly their performance and life limitations," Case says. With the RACV attending to 140 wheel changes per day last year in the Melbourne metropolitan area alone, that means a lot of cars are being driven on space-savers. RACV chief engineer Michael Case says nearly 25 percent of all new cars sold are fitted with the space- and weight-saving spares and the organisation is concerned that many people don't know the tyres' limitations. ![]() That is, if the car is one of the growing number from a range of manufacturers that are supplied with a space-saver - or temporary-use spare tyre, as they are more correctly known - to replace the traditional full-size spare wheel and tyre.Īccording to test data released by the RACV this week, the fitting of a space-saver wheel and tyre can substantially affect the emergency handling of a vehicle. It's not a rogue spider that snuck in from Japan, or a dodgy bit of wiring - no, it's the spare wheel and tyre. The manufacturer’s option offers a more effective installation than options offered by third parties: - Fixing the wheel to the floor (safety, noise) - Integrating the tool kit into a designated space (safety, noise) - Ensuring that the proposed wheel is compatible with the vehicle: brake changing, diameter, stability on braking and turning (safety, manufacturer’s warranty).ĭelivered in individual pieces.Hidden in the boot below the plush carpet or felt lining of your new car could be something that may significantly compromise your health and safety.A space-saver spare wheel maximises the boot’s loading capacity and makes it easier to change the wheel.It is recommended that the spare wheel tyre is replaced after each use.
